The supermarket chains used to seem unbeatable, capturing the lion’s share of the grocery market. But for some years now they have been in crisis. In the wake of a fierce price war, retailers are resorting to increasingly aggressive commercial negotiation methods at the expense of suppliers, farmers and producers. Further competition is coming from the tech giants as Amazon and Alibaba invest in the food industry. What are the implications of all these changes on working conditions, the quality of our food and the future of our planet?

This film tells the story of the economic war between the four main companies of the large retailers. This war symbolizes the transformation of the economy of the consumption over the last 50 years. It also questions the present and future stakes: how to imagine the 21th century's consumption style.

In the 19th century, China held the monopoly on tea, which was dear and fashionable in the West, and the British Empire exchanged poppies, produced in its Indian colonies and transformed into opium, for Chinese tea. Inundated by the drugs, China was forced to open up its market, and the British consolidated their commercial dominance. In 1839, the Middle Empire introduced prohibition. The Opium War was declared… Great Britain emerged as the winner, but the warning was heeded: it could no longer depend on Chinese tea. The only alternative possible was to produce its own tea. The East India Company therefore entrusted one man with finding the secrets of the precious beverage. His mission was to develop the first plantations in Britain’s Indian colonies. This latter-day James Bond was called Robert Fortune – a botanist. After overcoming innumerable ordeals in the heart of imperial China, he brought back the plants and techniques that gave rise to Darjeeling tea.
